2. Checking the heat exchanger (Once a year), (fig. 9)
After long times use dust may build up in the exchanger and block the airflow. It is vital to
clean the exchanger regularly to maintain high efficiency. The heat exchanger can easily be
taken out of the unit. Wash in hot soapy water. Do not use detergent containing ammonia.
Note! Make sure that the rotor motor is not exposed to moisture.
3. Checking the fans (once a year), (fig. 10)
Even if the required maintenance, such as changing of filters is carried out, dust and grease
may slowly build up inside the fans (E and F in fig. 2). This will reduce the efficiency.
The fans may be cleaned with a cloth or a soft brush. Do not use water. White spirit can be
used to remove obstinate settlements. Allow to dry properly before remounting.
4. Cleaning extract louvres and inlet diffusers (when necessary)
The system supplies fresh air to your home and extracts the used indoor air via the duct
system and diffusers/louvres. Diffusers and louvres are mounted in ceilings/walls in
bedrooms, living room, wetrooms, WC etc. Remove diffusers and louvers and wash in hot
soapy water as required. (Diffusers/ louvres must not be exchanged which will cause the
system to be balanced again).
5. Checking the fresh air intake, (fig. 6)
Leaves and pollution could plug up the air intake grille and reduce the capacity. Check the air
intake grille at least twice a year, and clean if necessary.
6. Checking the duct system (every 5 years), (fig. 7)
Dust and grease settlements may build up in the duct system even if filters are changed
regularly. This will reduce the efficiency of the installation. The duct runs should therefore be
cleaned/ changed when necessary. Steel ducts can be cleaned by pulling a brush soaked in
hot soapy water, through the duct via diffuser/ louver openings or special inspection hatches in
the duct system (if fitted).
NOTE! In addition roof cowl must be checked once a year and cleaned as necessary.
TROUBLESHOOTING
Should problems occur, please check or correct the following before contacting your service
representative.
1. Fan(s) do not start
Check that all fuses and plugs are connected (mains supply and fan plugs).
2. Reduced airflow
a) Check setting of airflow on control panel.
b) Change of filter required?
c) Cleaning of diffusers/louvers required?
d) Cleaning of fans/exchanger block required?
e) Is roof unit/air intake clogged?
f) Duct system. Check visible duct runs for damage and/or build-up of dust/pollution.
g) Check diffuser/louver openings.
